EARLIER THIS WEEK, FBI AGENTS WERE SEEN GOING OUT OF HIS BUILDING. WE CONTACTED THE FBI TODAY AND THEY DID ADMIT A ARE WORKING IN MANCHESTER, BUT THAT IS ALL THEY WOULD SAY. THEY WOULD NOT TELL US WHAT THEY ARE LOOKING AT GRADE BUT LOOK AT THIS BUILDING BEHIND ME. NEIGHBORS SAY THEY INTERVIEWED A MAN WHO LIVES IN THIS BUILDING. NEIGHBORS IN THIS QUIET APARTMENT TELL NEWS NINE ON A FORMER CHECHEN REBEL WHO LIVES HERE. TAMERLAN TSARNAEV VISITED HIM HERE. THIS MAN SAW THE FED AS THEY SEARCHED THE APARTMENT ON TUESDAY. HE GAVE AN INTERVIEW TO INTERNATIONALLY KNOWN NEWS AGENCY, VOICE OF AMERICA. HE SAYS SORRY I HAVE CAME TO HIS APARTMENT LESS THAN A MONTH BEFORE THE BOMBING. HE CAME TO MY HOUSE, BUT I BELIEVE THEY SAID HE IS COMING HERE TO NEW HAMPSHIRE AND I TRIED TO HELP HIM. AND HE INSISTS HE NEVER DISCUSSED POLITICS WITH THEM. HE DESCRIBED IN DETAIL HOW FBI AGENTS SEARCHED HIS APARTMENT. THEY SEARCHED THE HOUSE AND GOT MY FINGERPRINTS. IT IS EVERYTHING ALL ABOUT THE STATE OF NEW HAMPSHIRE. [INDISCERNIBLE] HE BOUGHT FIREWORKS HERE FROM NEW HAMPSHIRE. HE REFUSED TO ANSWER HIS DOOR WHEN WE APPROACHED TODAY. TAKING A LOOK AT YOUR LIVE IN MANCHESTER, THIS IS WHAT ELSE WE KNOW ABOUT THE MAN. HE CAME TO THE UNITED STATES AS A REFUGEE IN 2004.
